TOOL FOR SPLICING CABLES.

Application med February a, 1920. seriaim. 356,072.

To all whom t may concern Be it known that I, NEWTON K. BQWMAN, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Tools for Splicing Cables, of which the following is a specification.

This invention relates to a tool for splicing cables 'by means of a cable splicing member such as is set forth in my previous Patent No. 1,304,534, issued May 27, 1919.A

The invention also provides a tool whereby compressing dies are brought together on a cable splicing member previously placed upon the joined ends of the cable and the cable splicing member securely andfnally 1n p a l provide a splicin clampe ce.

A further object of the invention is to tool in which one or more cables may e accommodated simultaneously either for the purpose of splicing two cables contained in the same insulating covering such, for instance, as in a duplex cable, or for splicing one cable of a duplex cable without affecting the other, or for simultaneously splicing two different size cables.

Still another object of the invention is the provision of a tool having pivotally associated members, each of which carries part of a cable splice compressing die and part of an anvil whereby the complete tool forms bothl a cable splice compressing means and an anvil which may be easily carried around.

In the drawings:

Figure 1 is aview showingtwo separated'V cable ends in which the twist has been removed from the strands thereof;

Fig. 2 is a viewsimilar to Fig. 1 but with the cable strands flared;

Fig. 3 is a similar view with the cable strands oined in end-wise relation ready for splicing and with the splicing sleeve in position for slipping thereover; j

Fig. 4 is a view of the s licing tool with the cable in position for nally fixing the splice;

Fig. 5 -is a side elevation of the cable splicing tool.

In detail: A

With particular reference to Figs. 1 to 4 the ends 1 and 2 of a cable which is composed of the corewire 3 and the surrounding spiral strands 4 are cleared of their insula- 'tion 5 for! a short distance from each end and are tapped with a hammer on a suitable anvii 12 Such as will be hereinafter sa forth until the twist in the strands is removed. The strands are then flared from the core wire as shown in Fig. 2 and the core wire cut 60 back from one end so that the strands of the ends will lit together when the cable ends are brought in endwise relation as shown in Fig. 3, a splicing member 6 such as shown in my previously mentioned patent having been first placed over the cable as shown. After the ends have been brought together as shown in Fi 3 the splicing member 6 is placed over t e same and may substantially lill the gap between the in- 6 is completely contracted around the cable 80 splice the same may be wrapped with suitable insulating material such as tape or the like.

The splicing tool consists of the two'levers C and D pivotally associated at E. One of the levers C comprises a handleportion 8 having the die 9 integral therewith and carrying jaws 7 and 7a while the other handle member 10 has the die portion 11 integral.

therewith and carries the jaws 7 and 7h co- 90 operating with the prevlousl mentioned jaws 7 and 7a to form the ca le receiving passages F and G as indicated in Fi 5. The upper side of the die portion 9 vo the handle 8 isformed into an anvil head 12 95 while the lower side of the die portion 11 of the handle 10 is formed into an anvil seat 14V and thus the tool, when closed as shown in Fig. 5 forms an anvil having handles as indicated and the anvil portion of which may be rested on any solid surface'for use.

The handle members 8 and 10 are pivotally associated by reason of the fact that the eye 13 of the -member 8 coo erates with a similar eye 13 of the mem r 10 with a 105 pivot E passing through thetwo'.

In the splicing of a single cable such as is indicated in Figs. 1 to 4, the pro er size splicing jaws are selected forproper y compressing the cable splicing member 6 around 110 the cable. When the tool is used for repairing duplex cables in which one or both If desirable the splicing member 75 handle mem ers. each mcludin cables may be fractured, the s liced joint ofthe fracturedcable of the uplex cable is placed in the opening F for compression of the splicing member 6 'while the other cable is placed in the opening G. The advantage of this construction 1s that due to the proximity of the two passages `I4" and G the covering of the duplex cable need be cleared away from the broken ends onl a suicient distance to permit the two ca les to separate sulicientlyto seat in said pas -sages with the result that a neat. sub` stantial and practical repair may be effected without materially destroying the insulation of the duplex cable.

I claim: y A splicin tool com risin two lever a cylindrical shank and a head portion o rectanguaround and compress splicing elements, said flat faces abutting throughout their area on both sides of and between said passages when the tool is closed to limit the compression of the splicing'. elements, one of said headportions having a projection forming an anvil head and the other head portion having an anvil base; whereby a substantially solid anvil is produced on which preliminary and finishing work of splicing may be performed. y

In testimony whereof I aiiix m signature.
